T C P : k e e p a l i v e
Keepalive check cycle.
T C P : c o n n e c t s
Total number of connections established.
T C P : c l o s e d
Total number of dropped connections.
T C P : t i m e o u t d r o p
Total number of dropped connections due to TCP
retransmission timeout. When the transmitted
packet (the unit of transmitted data) is not
received, the packet is automatically
retransmitted at a predetermined time interval. If
the packet is not received after 14
retransmissions, timeout occurs and the
connection is dropped.
T C P : k e e p d r o p s
Total number of dropped connections due to TCP
keepalive timeout.
T C P : s n d t o t a l
Total number of transmitted packets.
T C P : s n d b y t e
Total number of transmitted bytes.
T C P : s n d r e x m i t p a c k
Total number of retransmitted packets.
T C P : s n d r e x m i t b y t e
Total number of retransmitted bytes.
T C P : r c v t o t a l
Total number of received packets.
T C P : r c v b y t e
Total number of received bytes.
D L C : 1 6 c o l l i s i o n s
Number of collision incidents. A collision occurs
when two or more instruments on the network
attempt to transmit simultaneously. The
tendency for collisions to occur increases when
the network is congested. 16 collisions would
mean 16 consecutive collision incidents.
quit
Disconnects the connection
of the instrument being
operated

4.10 Instrument Information
Output Commands
(Available when using the
instrument information
server function via

The instrument information server function interprets
one UDP packet to be one command and returns a
single packet (containing the recorder’s information) in
response to the command.
Port number 34264/udp
(see section 2.1)
Transfer data ASCII
Received buffer length
128
Transmit buffer length

Maximum number of parameters
32
In the command packet, parameters corresponding to
the desired information are placed one after another.
